Description
Technical field
The invention belongs to protective materials field, relate to a kind of impact resistant composite material fabric, particularly a kind of hybrid composite fabric preventing fiber slippage and cracking, can be applicable to the sandwich layer of anti-ballistic materials and the attaching parts of metal and nonmetallic materials.
Background technology
The shock resistance mechanism of high-performance fiber shock resistance fabric is mainly: when fiber is hit, shock wave energy rapid diffusion can be held, fibrous fracture time need absorb the energy that all will absorb alluvium in energy to failure, the distortion of sheet material integrally bending and the process such as interlayer slip thereof, these mechanism are common by the kinetic energy approach exhaustion of alluvium (as the swiftly passing object such as bullet, fragmentation), thus reach shock proof object.But by together with resin-bonded, very easily there is slippage when the thing that is hit impacts and loosen, causing rapid crack, shock wave energy diffusion hindered, cause high-performance fiber can not give full play to the advantage of self in fiber and fiber interweaving place.At present, mainly there are the following problems for composite shock resistance braided fabric: the position 1, be connected with metal parts is weaker, and poor thermal conductivity; 2, very easily there is slippage between fiber and loosen, the advantage of large energy when not giving full play to high-performance fiber fracture, can be absorbed.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, particularly for the shortcoming of existing shock resistance fabric poor heat conductivity, non-refractory, connecting portion weakness, provide a kind of and effectively can prevent the Quick Extended of the slippage between fiber and crackle, avoid fabric to be hit after mesh swell and be out of shape, good, the resistant to elevated temperatures impact resistant composite material fabric of heat conduction.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of impact resistant composite material fabric, described impact resistant composite material fabric is made up of steel wire mesh frame and the flexible fiber bundle be bundled on described steel wire mesh frame.
In above-mentioned impact resistant composite material fabric, preferably, described flexible fiber bundle is high-performance flexible fibre bundle, the TENSILE STRENGTH >=2000MPa of described high-performance flexible fibre bundle, fracture toughness >=1500mN/tex, elongation at break >=3%.

In above-mentioned impact resistant composite material fabric, preferably, described flexible fiber bundle weaves configuration in " N " type in the mesh cells of described steel wire mesh frame.
In above-mentioned impact resistant composite material fabric, preferably, described steel wire mesh frame is formed by steel alloy fibrage; The elastic modelling quantity of described steel alloy fiber is 200GPa ~ 210GPa, and shear strength is 450MPa ~ 600MPa, and heat resistance is 800 DEG C ~ 1000 DEG C.
In above-mentioned impact resistant composite material fabric, preferably, described steel alloy fiber is stainless steel fibre.
In above-mentioned impact resistant composite material fabric, preferably, the texture of weaving of described steel wire mesh frame comprises plain weave, twill or satin weave.
In the present invention, all scopes include endpoint value.
Principle of the present invention is as follows:
Tradition shock resistance fabric (as traditional shock resistance kevlar fabric) when being subject to impacting, failure mode main manifestations be the fracture of fiber and Fabric mesh distortion, swell, as shown in Figure 1.The fracture of fiber can absorb a large amount of energy, and this is favourable to shock resistance, but the distortion of Fabric mesh and swelling, make fabric lose impact resistance rapidly, thus make alluvium pass easily through fabric.The stressed schematic diagram of fabric unit as shown in Figure 2, single mesh cells (i.e. grid cell) is subject to the power F to surrounding extruding, due to the modulus of fabric and shear strength lower, fiber is wherein easy to deform and slippage (the A intertwined point in such as Fig. 2), can not give full play to the advantage of fiber; Meanwhile, when one of them mesh cells destroys, " reeling off raw silk from cocoons " phenomenon can occur, and the impact resistance of whole fabric declines rapidly, final generation moderate finite deformation and then inefficacy.
In order to improve the non-deformability of fabric, the stainless steel fibre braided fabric that hybrid composite fabric employing modulus provided by the invention is high, shearing strength is high, thermal conductivity is good or other steel alloy fibrous braid are skeleton, as shown in Figure 3 and Figure 4.When single mesh cells is subject to the power F to surrounding extruding, due to the modulus of fabric and shear strength higher, distortion is less likely to occur fiber wherein, shock wave energy rapid diffusion can be held, simultaneously the high-termal conductivity of stainless steel or other steel alloy heat rapid diffusion that impact can be made to produce, avoids local temperature rising.
But under larger extruding force F effect, still can there is slippage in fiber interweaving place, thus make mesh swell, and loses impact resistance; And when one of them mesh cells destroys, " reeling off raw silk from cocoons " phenomenon still can occur, the impact resistance of whole fabric also can decline rapidly.Therefore, the present invention considers stainless steel fibre intertexture place high-performance flexible fibre bundle to be carried out knotting binding, make slippage and cracking (such as bundling node 3 without slippage) no longer occur between fiber, each like this mesh cells also becomes independently unit, when one of them mesh cells destroys, other unit is unaffected, and this is also the basic reason that composite material fabric of the present invention has superior shock resistance.
The continuous winding weaving manner of high-performance flexible fibre bundle on steel wire, can not only improve intensity and the impact resistance of shock resistance fabric further, weaving of fabric can also be made to realize mechanized operation, thus realize industrialized mass production.One provided by the invention " N " type weaving manner as shown in Figure 4, high-performance flexible fibre bundle in independent mesh unit not only can improve the anti-extrusion ability of mesh greatly, the separate unit of quadrangle can be made to be partitioned into independent stable triangular structure unit further simultaneously, substantially increase the stability of fabric, thus play good shock resistance effect.
Compared with prior art, the invention has the advantages that:
1, the present invention adopts high-performance flexible fibre bundle to carry out tangled up and knotted binding at the intertexture place of steel alloy fiber reinforcement, each mesh of steel wire is made to become stable separate unit, effectively can prevent the Quick Extended of slippage between fiber and crackle, after avoiding fabric to be subject to bullet impact, mesh swells and is out of shape.
2, impact resistant composite material fabric of the present invention adopts steel alloy fibrage to become skeleton structure, has good, the resistant to elevated temperatures effect of heat conduction.
3, impact resistant composite material fabric of the present invention may be used for the parts preparing curved surface and other labyrinths, also can directly punch to be connected with miscellaneous part.
